ABSTRACT:
A fluid seal for ball control valves formed from a composition comprising a fluorinated resin, a reinforcing polymer, and, optionally, molybdenum disulfide, which has been compression molded in a tube mold, heat sintered and annealed. Such a formed ball seal has improved properties of chemical resistance, hydrolysis and creep resistance, a sufficient hardness for low wear, a reduced coefficient of friction, and is virtually nonabrasive.
